Everlasting Comfort Seat Cushion vs Dekun Orthopedic Memory Foam Seat Cushion

The Everlasting Comfort is the safer buy for most people. It has a long, well-documented record with over 12,000 ratings at 4.5 stars, a 2-inch high-density memory foam core, a non-slip rubber base and a machine-washable cover. The Dekun is a larger, thicker-looking L-shaped cushion aimed at truck drivers, but it has little independent feedback and its listed dimensions are inconsistent. Owners of the Everlasting Comfort praise tailbone and lower back relief but some find it softer and thinner than expected.

  • Choose the Everlasting Comfort if you want a proven, widely reviewed coccyx cushion for an office chair or car seat and value a non-slip base and washable cover.
  • Choose the Dekun if you drive a truck or sit in a deep bucket seat and want a bigger, more enveloping L-shaped cushion with a washable cover.

What reviewers say

Everlasting Comfort Seat Cushion

  • 4.5 / 512,287 ratings

Buyers rate it 4.5 out of 5 across more than 12,000 ratings and most praise all-day comfort and tailbone relief. The main complaints are that it is thinner and softer than expected and that a sticker leaves residue on the cover.

What people mention
  • ComfortPraisedBuyers say it stays comfortable through long days of sitting.
  • Pain reliefPraisedMany report less tailbone and lower back pain within a week.
  • CoverPraisedThe removable cover is called soft and easy to wash.
  • GripPraisedThe non-slip base keeps the cushion from sliding on chairs.

Questions and answers

Which is better for tailbone pain?
Both use a U-shaped coccyx cutout. The Everlasting Comfort has far more owner reports of tailbone relief, so it is the safer choice for that use.
Which lasts longer?
The Everlasting Comfort has a documented high-density foam core and washable cover, and its long review history gives more confidence in durability. The Dekun has too little feedback to judge.
Is the Dekun worth stepping up to?
Only if you need a larger L-shaped cushion for a truck or deep seat. For a standard office chair, the Everlasting Comfort fits better and is better proven.
Which is better for a truck driver?
The Dekun's larger L-shape is designed for truck seats. The Everlasting Comfort is smaller and may leave gaps in a deep bucket seat.
Do both have washable covers?
Yes. Both have removable, machine-washable covers. Air-dry the foam core rather than machine drying it.
Which stays in place better?
Both have non-slip bases. Owners of the Everlasting Comfort specifically praise its grip pad, so it has the stronger track record.
